2925           specified. This was wrong because wxWindows programs often assume
2926           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2927           it. To see why, you should understand that Windows sends WM_SIZE from
2928           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2929           from some base class ctor and so this WM_SIZE is not processed in the
2930           real class' OnSize() (because it's not fully constructed yet and the
2931           event goes to some base class OnSize() instead). So the WM_SIZE we
2932           rely on is the one sent when the parent frame resizes its children
2933           but here is the problem: if the child already has just the right
2934           size, nothing will happen as both wxWindows and Windows check for
2935           this and ignore any attempts to change the window size to the size it
2936           already has - so no WM_SIZE would be sent.
